Let's set some expectations
Docker helps developers
by providing solutions for
- "It works on my machine"
- Simpler and faster (and automated) Deployments
- Dependency Management
- Quicker technological improvements
- Reproducibility of environment (process)
- By keeping the environment..
.... hahaha ...
Docker helps sys admins
by providing ways to handle
- "It worked on my machine..."
- Managing environment changes
- Conflicting runtimes
- Log files and monitoring
- Reduction in complexity
- "Runs Anywhere"
Docker -
The Big Picture
- Ridiculous growth
- Open source engine
- Linux (and maybe? windows)
- Allows to create and share images
- Standard format
Demo
- Show you docker daemon on AWS
- Show you a Docker File (which is a DSL)
- Deploy simple HTML/JS/CSS application
- Make change and redeploy
